WANTAG E=ROD.

SPECIFICATION forming part of Letters Patent No. 480,058, dated August2, 1892.

Application filed May 26, 1892.

To all whom it may concern.-

Be it known that I, J OHN F. BARKER, a citizen of the United States,residing at Springfield, in the county of Ilampden and State ofMassachusetts, have invented new and useful Improvements in Gages, ofwhich the following is a specification.

The object of this invention is to improve the construction of a gagefor determining the depths of liquid in tanks to the end of renderingthe gage most simple and cheap of production, the same being entirelyadequate in the performance of the depth-measuring operation.

Reference is to be had to the accompanying drawin gs,in which iheimproved gage is shown.

Figure l is substantially a longitudinal section of the gage. Fig. 2 isa side View of same.

The invention embodies a bar A, of suitable length and material,the samebeing round, as shown, or it may be of other cross-sectional form, andis provided at intervals along its length with the pockets 1), havingtheir axes oblique to the length of the bar and all preferably openingto the same side of the bar, substantially as shown. The bar at itsupper end is preferably provided with an eye a for. the engagementtherewith of the hooked end of a rod or a cord, by means of which thebar may be suspended or lowered into the tank. or liquid-receptacle whenthe latter has a depth greater than the length of the bar. The pocketedbar may be produced by molding, a suitable core for the formation of thepockets being employed.

The mode of utilization of the liquid-depth gage is most apparent uponan inspection of the drawings, it being understood that upon thewithdrawal of the gage liquid will be also withdrawn in pockets up toand including the one which is as far above the lower end of the SerialNo. 434,446. (No model.)

gage as the top of the liquid is above the bottom of the tank. Thenecessity for a gage of this character is most frequently found when itis desired to ascertain how much of a liquid of an especially-volatilenature remains in a tank.

It is of course well known that for gaging depths of ordinary liquids aplain bar of. wood will suifice, the length of saturation indicating thedepth; but for such liquids as naphtha it is necessary to have the gagetake up such material quantities thereof as will not become dissipatedimmediately after the submerged portion of the gage has been withdrawnfrom the fluid.

I am aware that it is not broadly new to provide a gage having a seriesof pockets along its length, for I am aware that such a gage has beenconstructed, consisting of a small metallic rod, which has thereon alongits length (the rod being coincident with the axes thereof) a series ofmetallic cups, which are secured to the rod by soldering; but suchconstruction of the gage involves the employment and assemblage of manypieces, which assemblage, by soldering, is comparatively expensive; butI am not aware that a gage constructed substantially as hereinbeforedescribed and capable of production at a triflin g sum has ever beendevised; and therefore What I claim, and desire to secure by LettersPatent, is-

A liquid-depth gage consisting of a bar provided at intervals along itslength with a series of outwardly-opening pockets having their axesoblique to the length of the bar, substantially as and for the purposeset forth.
